Abstract

Telah dilakukan penelitian tentang pengaruh parameter fisis terhadap jumlah air yangmenguap di kota Pekanbaru. Metodologi yang digunakan dalam penelitian ini adalah metodestatistika regresi linier ganda. Data-data yang digunakan merupakan data sekunder yangdiperoleh dari Badan Meteorologi dan Geofisika Bandara Sultan Syarif Kasim II PekanbaruRiau. Dengan menggunakan metode statistika analisa regresi linier ganda, dapat diketahuiadanya pengaruh antara kelembaban udara, kecepatan angin dan suhu udara terhadap jumlahair yang menguap sehingga diperoleh nilai korelasi antara parameter fisis terhadap jumlah airyang menguap. Nilai korelasi ini menunjukkan hubungan yang kuat antara variabel-variabeltersebut yang diperhitungkan setiap bulan. Penguapan tertinggi tahun 2008 terjadi pada bulanOktober yaitu sebesar 4,9 mm dan penguapan terendah terjadi pada bulan juli yaitu sebesar3,9 mm dan penguapan tertinggi tahun 2009 terjadi pada bulan Maret yaitu sebesar 6,4 mmdan penguapan terendah terjadi pada bulan Februari yaitu sebesar 3,9 mm sedangkanPenguapan tertinggi tahun 2010 terjadi pada bulan Mei yaitu sebesar 6,9 mm dan penguapanterendah terjadi pada bulan Desember yaitu sebesar 3,5 mm.Keywords: Parameter Fisis, Jumlah Air, Penguapan

Abstract

Telah dilakukan penelitian tentang faktor-faktor fisis yang mempengaruhui akumulasi Nitrogen monoksida dan Nitrogen dioksida di udara Pekanbaru pada stasiun Kulim, Sukajadi dan Tampan dengan menggunakan metodologi interpretasi data. Pengabilan data akumulasi NO dan NO2 konsentrasi NO dan NO2 dilakukan dengan menggunakan alat Nitrogen Oksida Analyzer seri APNA 360 di Laboratorium Udara Kota Pekanbaru. Data yang diamati adalah data harian dari bulan Januari tahun 2010 sampai dengan bulan Desember tahun 2012 . Hasil penelitian menunjukkan bahwa konsentrasi NO dan NO2 tidak pernah sama di setiap bulannya. Konsentrasi terendah NO terdapat di stasiun Kulim sebesar 2,43 μg/m3 pada tahun 2012 dan konsentrasi tertinggi terdapat di stasiun Sukajadi sebesar 55,51 μg/m3 pada tahun 2010. Konsentrasi terendah NO2 terdapat di stasiun Tampan sebesar 3,99 μg/m3 pada tahun 2010 dan konsentrasi tertinggi terdapat di stasiun Sukajadi sebesar 92,99 μg/m3 pada tahun 2010. Suhu, kelembaban udara dan kecepatan angin mempengaruhi besarnya konsentrasi NO dan NO2. Suhu udara yang tinggi, kelembaban udara yang rendah serta kecepatan angin yang tinggi menyebabkan konsentrasi NO dan NO2 rendah, sedangkan suhu udara yang rendah, kelembaban udara yang tinggi dan kecepatan angin yang rendah menyebabkan konsentrasi menjadi tinggi.Kata kunci: Faktor-faktor fisis, akumulasi, suhu, kelembaban udara, kecepatan angin

Abstract

A research about measurement of the noise level in the Hydrocracker Area Complex Unibon Reactor Unit 211 PT Pertamina RU II Dumai particularly in the area of reactor, pump, and compressorhas been done. The noise level was recorded by direct measurement using two Sound Level Meters (SLM).The noise levels were measured as a function of time and distance. The results show that the highest noise levels occurred in the compressor area that is in the range of 93.685 to 93.689 dBA. While the average noise level that occurs in the area of the reactor, pump, and compressor as a function of time from 08:00 to 15:00 generates almost the same value. But on certain days and certain hours noise levels had a significant fluctuation. These fluctuations were caused by steam leaks in the connections of pipe. The results show that the level of noise as a function of distance from the source towards to the Maintenance and Campo reactor decline with the distance. The decrease in noise levels as a function of distance shown by the slopes of the graphs for maintenance and Campo reactor are -0.9939d+80,087 dan -1,71d+88,25 respectively. This slope indicates that the decrease of noise level for Campo reactor is faster than that in maintenance. This decrease is caused by the presence of sound absorption by vegetation around the area.Keywords: noise, reactors, pumps, compressors, time, and distance.

Abstract

A study concerning the determination of the quality of river water and well water around the river Siak using the experimental method has been investigated. This research was conducted by measuring the electrical properties of water at a temperature of 20 ̊C. The type of water used were water streams, water dug wells and water wells drilled in obtaining seven points. Measurement of the electrical properties of water was done by using multitester associated with power suppy, the plate of Copper (Cu) and Zinc (Zn) as a conductor, and the glass beaker as a container for the sample. The measurement will show voltage and current values. Based on voltage and current values,theycan calculate the value of the electrical properties of each sample. Results of river water has a resistance value of 2255.46 Ω, resistivity of 213.14 Ωm, conductivity of 0.00530(Ωm)-1, and power of 3.81 x 10-5 W. The electrical properties of best water wells dug well is six with a resistance value of 3136.46 Ω, resistivity 296.39 Ωm, conductivity of 0.00345 (Ωm)-1, and power of 7.85 x 10-5 W. Based on the results, the value of the electrical properties of the best water is the average electrical properties of water well three (drilled wells) with a resistance value of 3538.61 Ω, the electrical resistivity value of 334.39 Ωm, the electrical conductivity value of 0.00341 (Ωm)-1, and electric power of 4,76x10-5W. The water is suitable for consumption having a resistivity of 3x103 Ω, and the electrical conductivity of (300 to 500) x10-6 (Ωm)-1. Based on the standard resistivity and electrical conductivity, the river and well water samples are unfit for human consumption because the values are still far from the exposure limits.

Abstract

Water was a very important component for our life on this earth. The existence of water on earthwas limited by space and time. The purpose of this study was to analysis of the distribution ofthe soil water infiltration rate in the district of Bukit Raya Pekanbaru. Data used in the formof data from the measurement points coordinates, soil resistivity and lithology. The level ofground water absorption measured by coordinate points as much 20 points. The next, dataobtained input into the sofware “surfer 11” to be processed in order to obtain a contour mapsoil water infiltration rate. The results showed that the highest value of catchment located inthe village of Simpang Tiga in the amount of 119968,14 m3/year, where as the value of thelowest ground catchment located in the village of North Tangkerang that was 10054,47m3/year. Conclusion, the catchment area of land affected by open land and soil lithology.
